VL fog property can't set distance properly
Currently fog_start->SetValue( 0 ); and fog_stop->SetValue( 1000 ); can be set programatically, however when you try and alter them using the properties dialog you can only set values up to 99.99 as constrained by MITK's property interface. I'd suggest we change the units from mm to cm. We should then be able to set this to anywhere between 0 and 1 metre, with a resolution of 0.1 mm. Also change the default value to around 250 mm, (25cm). Any thoughts @mclarkson ?
